Other than the fact that packets 18 and 20 are writes to the same disk block, 
I don't see anything wrong in that trace.

I think Shao's suggestion to enable DEBUG=int13 is your best hope.  I suspect 
that "verify on" is causing your DOS to use INT 13,04 (or INT 13,44); these 
are not supported by gPXE but could trivially be added to just always return 
"success".  What puzzles me is that I can't reproduce your problem by using 
"verify on" in my own DOS setup.
